To elaborate on Dr Brian's explanation, a P.I.T. maneuver (Precision Immobilization Technique)the application of the front portion of the front quarter panel ahead of your patrol vehicle's tire against the rear portion of the back quarter panel of the fleeing vehicle. You steer into the fleeing suspect's vehicle to force the vehicle to turn perpendicularly to its direction of travel. Push-bars can be used to apply a PIT maneuver as well. Sorry for the paragraph. Haha.
